sorry, i found some part's spread is a bit uneven between oni and muzu:
01:00:621 (261) - this note could be removed to make the gap more close
00:35:314 (142) - ^
00:39:090 (156) - ^
01:10:621 (309,310,311,312,313,314,315,316,317,318,319,320,321,322,323,324,325,326,327,328,329,330) - this part should be less dense,
example00:59:192 (254,255,256,257,258,259) - consider to make this part less dense you may try to see the muzu's dense when you map.
muzu:
00:57:151 - could add note here to make the spread more close with oni
01:10:212 - ^
01:12:661 - ~01:13:886 - could add some note to make the gap more close with oni
01:00:825 (135,136,137,138,139,140,141) - could be more denser to make the spread more even,
examplemost of them are spread issue, oni's pattern is improved indeed but the gap between oni and muzu is a bit high on some parts ,try to take care of it, if you think you improve them, call me back again!
